SAFETY-ENVELOP.

Application led February 1, 1913.

To all whom t may concern:

Be it known that we, JAMES D. ODoNo- GHUE and iViLLrAM ODoNoGHUn, citizens of the United States, residing at New York, in the county of New York and State of New York, and MARGARET A. TRIGG, a citizen of the United States, residing at Vashington, in the District of Columbia, have invented new and useful Improvements in Safety-Envelops, of which the following is a specication.

This invention relates to a safety envelop; and it has for its primary object the provision of an envelop wherein the front wall thereof may be utilized to contain advertising matter, souvenir pictures or the like, while an opposite wall of the envelop is provided with a sealing tongue which is adapted for interlocking' engagement with the folded flaps and designed to be concealed by a postage stamp.

Another object of the invention is the provision of an envelop having sealing means which will positively prevent the sealing flap from being opened without detection.

Vith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings -Figure 1 is a front view of the envelop, showing the application of a postage stamp thereto so as to conceal the locking tongue; Fig. 2 is a similar view with the omission of the postage stamp; Fig. 3 is a section on line 3-3 of Fig. 2; Fig. 4c is a plan view of the blank; and Fig. 5 is a view similar to Fig. 4, showing a slightly modified form of the invention.` Fig. 6 is a similar view, showing another slightly modified form of the invention.

The envelop comprises a single blank of material, which is cut to provide a main wall 1, whose exterior surface is adapted to contain advertising matter, souvenir pictures or the like, a second wall 2. closing iiaps 3 and 4 and a sealing flap 5. The wall 2 is provided on its inner surface and preferably adjacent to all of its edges with an adhesive 6. |The flap is provided on its inner surface with an adhesive 7 which may be moistened and secured to an adjacent surface of the flap 3 when the latter is folded against the main body flap 1, while the ad- Specication of Letters Patent.

hesive 6 of the wall 2 is adapted to be moistened and secured to adjacent surfaces of the flaps 3 and ai when the latter are folded to the positions shown in Fig. 2.

Adjacent to one corner, the wall 9. is provided with a slot 8, which is adapted to aline with similar slots 9 in the flaps 3 and 4. The sealing flap 5 is provided with an adhesive 10 which may be moistened and secured to the outer surface of the.V wall 2. Said sealing flap is provided in its righthand corner with a tongue 11, which includes a relatively restricted neck l2 and a substantially arrow-shaped head 13 having portions extending into the sides of the neck 12, so as to present locking shoulders 14. This tongue has its head 13 provided with an adhesive 15 whichmaybe moistened so that it will adhere to the inner surface of the iap 3 when the tongue is inserted through the alined openings 8 and 9. A sealing element 16 such as a postage stamp may be placed over the tongue end of the sealing flap 5, so as to conceal said tongue and the receiving slots 8 and 9 therefor. From this construction it will be apparent that the adhesive of the stamp or sealing element 16 will in all probability adhere to the exposed neck 12 of the locking" tongue so that should one endeavor to obtain access to the contents of the envelop by first removing the stamp 16 it is possible that the neck 12 will in a measure be destroyed, whereby it will be visible to the receiver of the envelop that some one has been tampering with the same. The said neck 12 between the longitudinal edge 17 of the sealing iap 5 and the alined slots of the flaps 3 and t and the wall 2 is free whereby it may be readily destroyed when tearing the stamp or sealing element 16 from the cnvelop. By placing an adhesive 15 upon the described surface of the locking tongue, the adhesive will be concealed in such manner that it cannot be readily moist-cned when steaming or similar methods are resorted to with a view to gaining access to the contents of the envelop.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention, as claimed.

In the modified form of the invention shown in Fig. 5, the tongue 1la is of rectangular configuration and the corners 1lb are adapted for insertion through the folded Hap of the envelop and to be bent on the lines ll, whereby to form stops to engage against the inner Wall and thereby prevent the sealing flap from being Withdrawn Without destroying' the tongue.

In the modified form of the invention shown in Fig. 6, the sealing tongue Q0 is provided With over-lapping end portions 21 which may be secured together and Which are associated With the main body portion of the tongue, so as to define therewith a substantially V-pocket in which may be secured a strip of cardboard 22 or like material.

Having thus described our invention, What We claim is The herein described envelop comprising a rectangular main Wall, a second Wall united to one edge of the main Wall, closing iaps united to opposite end edges of the main vvall, one of said flaps being coextensive in length with the main Wall and the other flap being shorter, said flaps having. coincident slots, and a sealing Hap on the edge of the main Wall opposite that to which the second Wall is united, said sealing flap being provided near one end With a tongue the Width of which corresponds With the length of the slots, and said tongue having a broadened foldable head at its outer end for insertion through the slots.

In testimony whereof We aiiiX our signatures in presence of tWo Witnesses.
